27 Claims,

This'invention relates to the manufacture ofl shoes and is illustrated as embodied in a heel-seat tting machine. It has been proposed to position a sole, attached to a shoe upper, lengthwise in a heel-seat fitting machine by the use of aback gage against which the rear end of the shoe upper isv forced and' the movement ofwhich, u nder pressure of the shoe upper, is limited by a measuring stop. sometimes the practice operatively to connect the stop with a movable abutment of a gage which measures the length of. the attaching face of a heel to be attached to the shoe upper. In order to position the heel in the heel gage the operator places the heel, attaching face downwardly, upon a table and then swings a hand lever which slides thev abutment over the table into engagement with the rear end of the rim of the attaching face of the heel and forces the breastA of the heel against a stationary abutment of the gage, connections being provided to position the measuring stop in accordance with the position of the slidable heel-engaging abutment. Such a construction is disclosed in United States Letters Patent No. 1,980,371, granted November 13, 1934 on an application filed in the name of Earl A,

Bessom.

In order to expedite the positioning of a heel in the heel gage and in accordance with a feature of this invention the illustrated machine comprises a gage provided with a movable abutment for measuring a heel, a movable back gage constructed and arranged to be engaged by the rear end of a shoe upper, and mechanism operable under pressure of the heel against the abutment constructed and arranged to determine the operative position of the movable back gage-in accordance with the length of the heel.

In the illustrated construction the mechanism which is operable under pressure of the heel against the movable abutment of the heel gage comprises a stop which limits the rearward movement of the back gage. The stop, which is In order accurately to position the' stop t is' r mounted for movement about an axis, is providedl (Cl. 12e-31.5)

mallyV urged toward a stationary abutment of the heel gage until astud carried by the stop engages a xed member. To reduce the tendency'of the stop being moved about its axis under pressure of the back gage the axis oi the stop is arranged substantially in alinement with the path of movement of the back gage. In order to insure that the heel measured by the movable abutment shall be securely forced against the table of the heel gage and in accordance with a further feature of this invention the illustrated machine is provided with a heel holddown.

In order to remove the chip which is trimmed from the heel-seat portion oi the sole and is left uponfa sole-supporting plate of the machine, the illustrated machine, in accordance with another feature of the invention, is provided with an ejector bar which is mounted for movement in a predetermined path and is supported by and in engagement with the sole-engaging surface of the plate, the bar being mounted for movement about anaxis disposed at a substantial angle to said path thereby to permit the bar to engage the sole-supporting surface throughout its travel. The ejector bar is operated through a spring and, in order to insure that the chip is pushed from the sole-supporting plate instead of being thrown from the same, cushioning means which opposes the spring is provided.

These and other features of the invention, including certain details of construction and combinations of parts, will be described as embodied in an illustrated machine and pointed out in the appended claims.

The invention is illustrated with reference to the heel-seat tting machine disclosed in United States Letters Patent No. 1,980,371, above referred to, and is provided with a crease plate 20 having a U-shaped opening 22 (Figs. 4 and 6)` and formed and arranged to be positioned between a shoe upper and the heel-seat portion of a sole attached to the shoe upper. In order to position the sole widthwise and lengthwise of the crease plate 2? the machine is provided with a bifurcated centralizing slide 24 and a back slide 26 constructed and arranged to vengage the sides and the rear end respectively of the counter portion of the shoe upper. The construction and operation of the slides 24, 26 will later be described in detail.

After the heel-seat portion of the sole has been positioned upon the crease plate 2E! a U-shaped clamp 28 is lowered to force the margin of the heel seat portion of the sole against a beveled crease plate surface 30 (Figs. 4 and 6) surrounding the U-shaped opening 22. While the margin of the heel seat portion of the sole is clamped against the crease plate 2() a bulger 32 (Fig. 2) is lowered to force the central part of the heel-seat portion of the sole through the opening 22 and below a bottom planar face 34 (Fig. 5) of the crease plate.

The clamping and the bulging operations above described are performed by lowering a rod 36 (Fig. 1), the bottom end of which is connected to a foot treadle (not shown). The upper end of the rod is pivotally secured to a rocker arm 38 which is mounted upon the main frame 40 of the machine and operates another rocker arm 42 through the provision of a connecting link 44 having a depending extension 46. The depending extension 46 is used to actuate a chip ejector, as will later be explained in detail. The forward end of the rocker arm l2 is pivotally connected through alink 48 and a coupling 53 to a plunger rod 52 to the bottom of which the bulger 32 is secured.

The U-shaped presser member 28 is `supported within a housing 54 (Figs. 1 and 2), an upper extension 55 of which engages a spring 58 enclosed within an inverted casing 58 secured for movement with the rod 52. The housing 54 is raised with the bulger 32 away from the work by a fiange (not shown) carried by the plunger rod 52. When the operator rst depresses the treadle the presser member 28 is lowered under foot pressure to clamp the margin of the heel seat portion'of the sole against the beveled surface 38 of the crease plate 32. Further depression of the treadle causes a power-operated cam (not shown) to lower the rod 35, thereby to force the bulger 32 downwardly until the casing 56 engages` a boss 62 of the main frame. When the casing 60 engages the boss 62 the lower sole-engaging face of the bulger 3'2 is located slightly above the lower face 34 (Fig. 5) of the crease plate 20. Any further movement of the treadle causes a. safety spring 64 (Fig. 1) carried by the rod 36 to be compressed.

straight cutting edge 68 in engagement with the' lower face 34 of the crease plate, trims the margin of the heel seat portion of the sole by a beveling cut.

Heel-breast receiving shoulders are formed upon the sole by shoulder-forming cutters 10 (Fig. 1) carried by a cutter carrier 12 which is adjustably secured to a slide 14 mounted for reciprocation along a guideway 16.

The heel-seat reducing cutter 66 is adjustably secured to a cutter carrier 1| (Fig. 5) connected by a screw 13 to a slide 18 (Figs. 1 and 5) movable forwardly and rearwardly of the machine along a guideway 88 of the main frame 48. The slide 18 is operated by a bell-crank lever 82 pinned to a shaft 84 mounted upon a bearing 86 supported by the main frame, the lever being connected to the slide 18 by a link 88 and to an operating cam (not shown) by a rod 90. The shoulder-forming cutters 18 may be operated either before or after the heel-seat portion of the sole has been reduced.

The heel-seat reducing cutters 66 and the shoulder-forming cutters 10 are automatically operated by power when a lever (not shown) is tripped by the treadle. As above stated, the mechanism for clamping and distorting the heelseat portion of the sole as well as the mechanism for trimming the sole is clearly illustrated and described in United States Letters Patent No. 1,980,371, which should be referred to for a complete understanding of the construction and operation of the machine.

VRearward movement of the centralizing slide 24 and the back slide 26 under pressure of the shoe is limited by a stop 92 through mechanism which will be described later, the stop 92 being rotated to a predetermined position in accordance with the size of a heel 94 (Fig. 8) positioned in a heel gage. The mechanism for positioning the shoe lengthwise in the machine will be rel ferred to as a back gage and the mechanism for positioning the shoe widthwise will be referred to as a centralizing gage. In lorder to reduce to a minimum lost motion on the part of the operator it is desirable to insert the heel in the heel gage under pressure of the heel, the operator then having only to pick up the heel which is to be applied to the shoe and to set it in the gage. Accordingly, an abutment 96, which is mounted for sliding movement along a guideway 98 (Fig. 3), is engaged by the rear end of the rim of the attaching face of the heel and is pushed rearwardly under pressure of the heel until the heel may be placed attaching face downwardly upon a table |82 between the sliding abutment 96 and a stationary breast plate or abutment |80. The sliding abutment 96 is normally urged toward the breast plate H1B by a spring E84, the arrangement being such that when the heel has been placed attaching face downwardly upon the table H32 the breast of the heel is forced against the breast plate 188 by the sliding abutment 96 and is thus properly oriented upon the table. The heel is thus clamped between the forward and rear abutments 96, |98 and is measured lengthwise in the heel gage.

The back slide 26 is movable forwardly and rearwardly of the machine along a straight groove IBS (Fig. 4) formed in the lower surface of a stop plate |88 which is mounted for movement in a pair of opposed rectilinear guideways H0 of the main frame. The centralizing slide 24, the work-engaging faces l I2 of which are positioned at equal distances from a median plane H4 (Fig.

3), is also mounted for movement along a pair of opposed guideways H6 arranged parallel to Iand positioned just above the respective guideways -|'|0. The centralizing slide 24 iis Ynormally urged forwardly of the machine against an upvstanding lug i8 o-i the stop plate |08 by a/spring |20 enclosed within a Yrecess of the centraliz'ing slide and engaging the forward portion of a rod |22 which enters the recess. The rear end of the rod |22 engages a bracket |24 (Fig. 3) secured to the main frame by screws |26. The back slide 26 is provided with an elongate slot |28 (Figs. 4 and 5) and is normally urged forwardly of the stop plate |06 by a spring |30 until a shoulder of the yback slide engages the Yrear face of the stop plate |08.' Extending through the elongated sli-de |28 is -a block |32 supported by a screw |34 in threaded relation with the stop plate |68 and surrounded by a sleeve |36 which passes through an arcuate opening |38 (Fig. 4) formed in the block |32. A depending pin lll-01s secured to the stop plate |08 and enters 'a circular recess of the block |32, the arrangement being such that the block |32 may be swung relatively to the stop plate |08 about the pin |40 within limits determined by the arcuate opening |38. f A depending rod |42 is carried by the block |32 and is arranged vto engage the main frame 40 to limit forward movement of 'the block. The block |62 is provided at its rear end with a concave cylindrical surface covered by a piece of facing material |44 having a relatively high coefficient of friction and constructed and arranged to engage the operating face |48 of the stop 92, which face has the form of a spiral of Archiimedes. It will thus be clear from the foregoing that the centr-alizing slide 24 is normally urged forwardly `of the machine by the spring |20 and forces the stop plate |08 forwardly until the rod |42 carried by the block |32 engages the main frame 48. As above stated, the back slide 26 is normally positioned forwardly of the stop plate |66 by the spring |00. When the shoe is presented to the machine rear end first and bottom side up, the sides of the counter portion of the shoe upper engage the respective work-engaging faces |l2 of the centralizing slide 24to position the shoe widthwise and as theshoe is moved rearwardly, the rear end of the counter portion of the shoe upper engagesthe back slide 26 and forces the same, together with the centralizing slide 24,

rearwardly until the facing material |44, which y may be made of leather, engages the spiral face |46 of the stop 92.

The stop 92 is mounted for rotary movement about a bearing |46 secured to the frame of the machine, the axis of the bearing lying in the plane lill. By providing the stop 92 with a face |46 having the form of a spiral of Archimedes it will be clear that for equal angles of swing of the stop, the face |46 of the stop crossing the plane ||4 will move equal distances forwardly and rearwardly of the machine.

As above stated, it is desirable that the stop 02 shall be swung to the proper position under the rearward pressure of the heel against the sliding abutment 96, without exerting too great a pressure upon the heel. Accordingly, the stop 92 is rotated by a gear |50 (Fig. 3) which is pinned to the sto-p 9?. and meshes with a geared segment |52 provided with a hub portion 54 which straddles a boss 566 (Fig. l) of the main frame and is mounted upon a shaft |53 rigidly supported by the boss. The hub portion |54 of the geared segment |52 is provided with an extension |58 (Fig. 3) pivotally connected to an angular arm it-0 which is adlustably secured to the sliding abutment V66 of the heel gage by a screw |62.. Since the abutment 96 is connected directlyV to the extension |58 the guideway '68 along which the abutment 96 slides is slightly wider than the abutment to permit the same to be shifted laterally a small amount.

The stationary breast plate |00 (Fig. 8) is held against `the table by a screw |64 which passes through an opening in the plate and is in thread- Yed engagement with 'the table |02. The brea'st plate I 00 comprises a flat face |66 for engaging the projecting lip or the breast of a Louis heel and a convex face |68 inclined to the table and constructed an-d arranged to eng-age the concave breast of a Cuban heel. The bottom 'side of the stationary plate |00 is provided with a V-shaped recess |10 within which a spring-pressed plunger (not shown) engages. The stationary plate |00 may be readily turned in accordance with the type of work being operated upon, the springpressed plunger serving properly to locate the plfate :|00 and to retain the lsame in operating position. When the heel is removed from the heel gage the sliding abutment 96 is forced vforwardly by the torsional spring |04 until a pin |12 (Fig. 3) carried by the stop 92 engages a fixed pin or member |14 secured to the main frame 40, the upper end of the -spring being secured to the hub |54 of the geared segment |52 and the lower end of the spring being secured to a ange |16 of the shaft |53.

Friction between the parts of the mechanism for setting the stop 92 in the proper position is reduced to a minimum so that excessive pressure is not exerted upon the heel being placed in the gage. The mechanism connecting the sliding abutment 96 with the stop 92 is so connected and arranged that the effective portion of .the 'spiral face |46 moves forwardly or rearwardly with and to the same extent as the sliding abutment 96.

In order that the operator may ascertain at a glance when the block |32 has been forced against the spiral surface |46 of the stop 92, a laterally extending bar |18 (Fig. 3) is secured to the rear -end of the back slide 26 and carries `at its outer end an adjustable indicator rod slidingly supported in the frame of the machine and disposed in parallel relation to another rod |82 which is secured to the angular arm |60. As illustrated in Fig. 3 the rod |80 extends 'forwardly of the rod |82 when there is no work in the machine. When a shoe has forced the block |32 against the stop 92 the forward ends of the respective rods |80, |82 are in alinement.

It will be noted that since the axis about which the stop 92 is rotated is located in the plane |44 there is little tendency for the rearward pressure of the shoe against the back slide 26 to turn the 'stop about its axis.

After the operator vhas placed the heel 94 attaching face downwardly upon the table |02 it is customary to release the heel and to permit the same to be forced forwardly under pressure of the spring |04 until the breast of the heel engages the stationary plate |00. It has been found by e'xperience that the weight of the mechanism connecting the sli-ding abutment 96 and the stop 92 should be reduced toa minimum in order that the heel shall not be injured as it is clamped 'in position. Accordingly, the Jstop 92 and various other parts of the stop-operating mechanism are preferably made of aluminum.

`Since 'the face |46 of the stop 92 has the form of a spirall of Archimedes it willv be clear that i1 sufcient pressure is exerted against the face, and

Vif there is substantially no friction between the block |32 and such face, the stop 92 is likely to swing even though the axis about which the stop is rotated is included in the vertical plane 4. Moreover, in order that the face |46 of the stop 92 shall not be dented it is desirable that the stopengaging face |46 of the block |32 shall be made of material softer than aluminum. It has been found'by experience that when the rear concave cylindrical surface of the block |32 is covered with leather facing material |44 satisfactory results are obtained, the friction between the block and the face |66 being sufiicient to prevent the stop from turning under rearward pressure of the block. The radius of curvature of the stopengaging face |46 of the block |32 is such that there is substantially line contact between the block and the lowest portion of the spiral face |46 and there is surface contact between the block and an intermediate portion of such face. Only the ends of the stop-engaging face |46 of the block |32 engage the highest portion of the operating face |46, the block being pivotally mounted to permit such engagement and also to permit the stop-engaging face of the block to be in surface engagement with the intermediate portion of the face E46. The slight error due to the block having line surface and two-point contact with different portions of the face |48 of the stop 92 is so slight that it may be disregarded. It will be noted that the error would be greater if the block |32 were not permitted to swing about the pin E48, as above described.

In order to position the shoe in the machine the operator places the heel to be attached to the shoe in the heel gage by forcing the rear end of the attaching face of the heel against the sliding abutment 96 and after placing the attaching face of the heel downwardly upon the table, the abutment 98 under pressure of the spring |04 forces the breast of the heel against the stationary plate |88. Forward movement of the abutment 98 through mechanism above described causes the Astop 92 to swing to a predetermined position. The shoe, bottom side up and rear end rst, is then moved rearwardly of the machine, the side of the counter portion of the shoe rst engaging the faces I I2 of the centralizing slide 24. As the centralizing slide 24 is moved rearwardly, the rear end of the counter portion of the shoe upper is forced against the back slide 26 and moves the same rearwardly with the centralizing slide 24 until the block S2 .is forced against the spiral face |48 of the stop 92. The operator then glances atthe rods |86, |82 to insure that the same are in alinement.

In order to remove from the machine a U- shaped chip which is left upon the crease plate 20 after the heel-seat portion of the sole has been trimmed by the heel-seat reducing cutter 66 and the shoulder-forming cutters i8, the illustrated machine is provided with an ejector bar |84 (Figs. 2 and 6) which is constructed and-arranged to engage the crease plate 20 as it moves over the same. The ejector bar |84, which is slightly curved in accordance with the opening 22 of the crease plate, is trunnioned upo'n a slide |86 (Fig. 6) movable forwardly and rearwardly along a guide |88. Extending from the slide |86 is a pin |90 constructed and arranged to engage within an elongated slot |92 (Fig. 1) of an operating arm |94 which is mounted upon a shaft |96 carried by the Ymain frame and has extending from its upper end a lug |98 arrangedto engage a stop` 200. A spring 202 normally retains the ejector bar |84 rearwardly of the sole-supporting portion of the crease plate 20. The upper end of the operating arm |94 is also provided With a forward lug 204 which is constructed and arranged toV be grasped by a hook end 206 of a reciprocating lever 208 in order to swing the operating arm |94 in a counterclockwise direction (Fig. 1).

The ejector bar |84 is normally supported by the crease plate 20. When the crease plate 28, however, is removed from the machine after pulling a plunger-pin 2|0 (Fig. 6) from engagement within a recess of the crease plate, the bar |84 is supported by a bifurcated lug 2|2 of an arm 2 4. From the foregoing it will be clear that the ejector bar |84, unless moved forwardly by the reciprocating lever 208, is held rearwardly of the sole-supporting portion of the crease plate by the spring 202. It is necessary to raise the presser member 28 and the bulger 32 away from .the crease plate 28 before operating the ejector bar |84.

The hook end 206 of the lever 288 is moved forwardly of the lug 204 of the operating arm |94 during forward movement of the heel-seat reducing cutter 66 but is not released until after the presser member 28 and the bulger 32 have moved out of the path of movement of the ejector bar |84. The lever 208 is provided with a bottom cam surface 2i 4 (Fig. l) which engages a roll 2 6 positioned in a notch of the main frame, the lever 288 being pivotally secured at its rear end to a .piston head 2 i8. A piston 220 to which the head 2|8 is secure-d is constructed and arranged for sliding movement in a cylinder 222.

The purpose of such a construction will be explained later. A coiled spring 224, opposite ends of which engage pins 226 and 228 of the lever 208 and the piston head 2 I8, respectively, at all times retains the cam surface 2M of the lever 208 in engagement with the roll 2 i6. A projecting portion of the cam surface 2|4 of the lever 208 causes the same to be raised when in a rearward position as illustrated in Fig. 1.

In order to move the leverl 288 forwardly, the cutter-operating slide 'I8 is provided with a laterally projecting flange 238 which upon forward movement of the slide, engages a depending portion 232 ofthe piston head 2|8 and forces the same, together with the lever 288, forwardly of the machine against the pressure of a strong spring 234. When the lever 288 has been moved forwardly of the lug 284 the hook end 286 of the lever drops into lowered position in front of the lug. When the piston head 2|8 moves forwardly a trip lever 236 (Fig. '7) which is pivotally mounted upon the main frame and has its front end normally forced downwardly by a spring 238, engages the rear part of the piston head 2|8 and temporarily holds the reciprocating lever 208 in a forward position.

When the presser member 28 and the bulger 32 have been raised a predetermined distance about the crease plate 28, the depending portion 46 (Fig. l) of the link 44 swings the trip lever 236 against the pressure of the spring 238 and causes the lever 288, lforced rearwardly by the spring 234, to swing the operating arm |94 in a counterclockwise direction, thereby to move the ejector bar |84 forwardly across the crease plate 20. As the depending portion of the cam surface 2|4 of the lever 288 rides up the roll 2| 6, the hook end 206 of the lever slides y01T the lug 204, and the operatingarm |94, urged by the'springY 202, moves in a clockwise directionuntil stopped by engagesage of air from the inside of the cylinder as the piston is moved rearwardly under pressure of the spring 234. Such a construction provides a cushioning effect which insures that the chip is pushed slowly from the plateinto a' container instead of being thrown fromthe crease plate 20. i

Because of the angle which the face |68 (Fig.

8) of the stationary plate I 00 forms with'the heel-supporting surface lof the table |02, the heel l is sometimes lifted at its forward end under pressure of the sliding abutment 96 and accordingly the face |58 may be faced with material vwhich will tend to prevent the forward end of the heel from being lifted from the plate. To insure, however, that the heel is held securely against the table |02, a holddown 245 which engages the tread end of the heel may be provided. In the illustrated construction` the ho-lddown 246 which carries a rubber roll 248 is mounted for swinging movement upon a bracket 252 secured 'to the table |02 and is normally urged toward the table |02 by a coil spring 250. A'guide 254 is carried by the bracket' 252 and is constructed and arranged to receive a slide 256 which is normally urged forwardly by a spring 25B to cause a pawl 260 formed integrally with theslide to engage a serrated portion 262 formed at the rear end of' the holddown 246 and thus limits the downward,

movement of the holddown.
